BUT the SCOTOMIA differs from the VERTIGO, in that besides the _Imagination_ of the _circular Motion_, the PATIENT often loses his _Sight_, staggers, tumbles, or falls to the Ground. And yet the _same_ is distinguished from the _Epilepsy_, in that the PATIENT retains his principal _Functions_, and neither _Foams_ at Mouth, nor is _Convulsive_.
HOWEVER, as to the _Distinction_ of Causes, if the _internal Cause_ proceeds from _Calidity_, it is known by the _hot Temperament_ of the whole Body, as well as by a _Swelling_ and _Pulsation_ of the ARTERIES about the _Throat_: Besides that this VERTIGO easily _accedes_ and _recedes_, it is always attended with _Calidity_ and _Redness_ of Face and Eyes; with _Watchings_, _Deliriums_, &c: And it commonly follows _Fevers_, _Watchings_, _Anger_, the _Use of Calids_, hot Things, _&c._ In which _Cases_, it is always to be helped by the _Use of Frigids_, or Coolers.
IF it arises from _frigid Flatulencies_, the _Paroxysms_ or Fits are preceded by a _Hissing_ or _Tingling_ in the EARS; the PATIENT turns _pale_ and _wan_, and is taken with an odd extensive _Pain_ of the HEAD: And if these _Flatulencies_ generate in the HEAD, the _Party_ feels it _ponderous_, _lumpish_, and _heavy_; and is consequently much inclin’d to _Sleep_, _Stupidity_, _Dullness_, and _Inactivity_.
IF the _Distemper_ is derived from a _flatulent Stomach_, the _PATIENT_ is troubled with _Rifting_ and _Rumbling_ of the Belly; with _Sobbing_ and _Sighing_, with _Hickups_, _Yawnings_, _Extensions_, _Inflations_, and frequent _Spittings_.
IF it comes from a _Mordacity_ of the _Mouth of the Stomach_, the _Party_ is infested with a _Nausea_, _Loathing_ and _Fastidy_; with a Dejection of _Appetite_, a lasting or frequent _Thirst_, and a _Bitterness_ of the Mouth. But this _Affection_ also very often proceeds from the WOMB, and that either because of the suppress’d _Menstrua_, or longretain’d _Seed_; as will hereafter more fully appear in _Sect._ ix. _Chap. 8_.
AS to the _Prognosticks_ of this _Distemper_, it does not always seem _Dangerous_, much less _Lethal_, at first; but its _Consequences_ are (however) very _Fatal_[69], if not timely prevented: For it often turns to _Inflammations_[70] of the HEAD, or _Convulsions_; sometimes to _Melancholy_ or _Madness_; and sometimes to _Epilepsies_ or _Apoplexies_.
